FIELD OF THE INVENTION

[0001] The present invention relates to a backup power supply apparatus and particularly an apparatus for absorbing light source and generating electric power output required by a load.

BACKGROUND OF THE INVENTION

[0002] These days, most known electric devices (or loads) such as notebook computers, handheld computers, camcorders, digital cameras, Global Positioning Systems, walkmans, CD players, MDs when in us indoor, in order not to waste electric power of batteries or charge batteries, users usually utilize transformers or voltage converters provided from the electric devices to plug in city power of 110V/220V AC to convert to DC power to supply the electric devices. When the electric devices are used outdoors and no city power is available, then the charge batteries contained in the electric devices will provide electric power needed. Thus the electric devices can meet the portable purpose for users to carry around.

[0003] However, the portable electric devices have a common problem, i.e. when used outdoors, the charge batteries could run out of electric power, and no city power is available nearby to plug the transformers or voltage converters, or no stores are located nearby for purchasing batteries. As a result, the electric devices could become useless and cause a lot of inconveniences.

[0004] The primary object of the invention is to resolve the foregoing disadvantages. The invention utilizes a light source absorbing device to absorb light source for immediately generating electric power to supply the load.

[0005] Another object of the invention is to provide a foldable, small size and light weight apparatus to facilitate users carrying for outdoor use.

[0006] A further object of the invention is to provide an apparatus that creates no environmental protection or recycle problems.

[0007] Yet another object of the invention is to provide an apparatus that can supply electric power to a load in the event of disasters to allow users to emit rescue signals through the load for seeking help.

[0008] In order to achieve aforesaid objects, the backup power supply apparatus of the invention includes a light source absorbing device and a casing for housing the light source absorbing device. The light source absorbing device can absorb light source and generate electric power output which may run through a charge circuit, a charge battery and a voltage conversion circuit to generate required electric power to supply the load.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Referring to FIG. 1, the backup power supply apparatus of the invention includes a light source absorbing device 1 and a casing 2 for housing the light source absorbing device 1. The light source absorbing device 1 may receive light source and generate an electric power output which may run through a charge circuit, a charge battery and a voltage conversion circuit to become an electric power supply for a load (such as a notebook computer, a handheld computer, a camcorder, a digital camera, a Global Positioning System, a walkman, a CD players, a MD, a handset) to use.

[0017] The light source absorbing device 1 includes at least one light source absorbing element 11 which may be a solar energy panel. The solar energy panel is a conventional technique and known in the art, thus its construction and principle are omitted here. Each light source absorbing element 11 has one end formed two corresponding first pivotal shafts 12. Each first pivotal shaft 12 has an inner end formed a first pivotal section 13 and an outer end formed a first pivotal cavity 14. The light source absorbing element 11 has another end formed a second pivotal shaft 15. The second pivotal shaft 15 has two ends formed respectively a jutting stub 16. The jutting stub 16 may be pivotally engaged with the first pivotal section 13 of the first pivotal shaft 12. Hence every light source absorbing element 11 becomes foldable. Each light source absorbing element 11 further has a conductive element 17 to transmit electric power to a neighboring light source absorbing element. The conductive element 17 may be, but not limited to, a pliable flat cable or conductive contacts located on the edge of the light source absorbing element 11 (the conductive contacts are located on positions connectable with one another when every light source absorbing element 11 is extended).

[0018] The casing 2 includes a first cap 21 and a second cap 22 which have respectively a first pivotal lug 211 and a second pivotal lug 221 corresponding to each other. The pivotal lugs 211, 221 have respectively a first pivotal aperture 212 and a second pivotal aperture 222. The first pivotal aperture 212 and second pivotal aperture 222 may match the first pivotal cavity 14 located on the outer end of the light source absorbing element 11, then is fastened together through a stub shaft 23 for coupling the light source absorbing element 11 to the casing 2. Every light source absorbing element 11 may be folded and housed inside the casing 2 to become a compact size to allow users to carry easily outdoors for use. Thus in the circumstances of no backup battery or city power, the apparatus can absorb light source to supply the load with required electric power.

[0019] Referring to FIGS. 3 and 4 for the invention in extension and folding conditions. As shown in the drawings, when an user carry the backup power supply apparatus outdoors, and the main power supply of the notebook computer, handheld computer, camcorder, digital camera, Global Positioning System, walkman, CD player, MD, or handset are running out, and no backup batteries are available, or no city power of 110/220V AC is available for converting to DC power, the user may utilize the backup power supply apparatus. When in use, unfold the casing 2, then extend individually the light source absorbing element 11 of the light source absorbing device 1 to absorb light source. The light source absorbing element 11 receives light source projection and provides an electric power output to supply the load for use.

[0020] When the backup power supply apparatus is not in use, fold the light source absorbing element 11 one by one, and place them respectively into the first cap 21 and the second cap 22, then fold the caps 21, 22 to house the light source absorbing device 1 completely inside the casing 2 to facilitate carrying for the user.

[0021] Referring to FIG. 5 for the process of power supply conversion of the invention, the charge circuit 3, charge battery 4 and voltage conversion circuit 5 disclosed in the drawings are conventional techniques known in the art, thus details are omitted here.

[0022] When every light source absorbing element 11 of the light source absorbing device 1 is unfolded to receive light source, electric power generated by each light source absorbing element 11 will be delivered to the charge circuit 3, the charge circuit 3 than charges the charge battery 4, the charge battery 4 will release electricity to the voltage conversion circuit (transformer or power supply converter) 5 to change the voltage for providing required power supply to the load.

[0023] Moreover, electric power generated by the light source absorbing device 1 may be directly output to the charge circuit used by the load to allow the charge circuit of the load directly charging the charge battery used by the load, or directly provide power supply to the load.

[0024] In addition, electric power generated by the light source absorbing device 1 may also be directly output to the voltage conversion circuit used by the load to allow the voltage conversion circuit of the load directly providing required power supply to the load.

[0025] Referring to FIG. 6 for another embodiment of the invention, the charge circuit 3, charge battery 4 and voltage conversion circuit 5 are directly installed in the casing 2. Electric power output from the light source absorbing device 1 is directly transferred through the charge circuit 3, charge battery 4 and voltage conversion circuit 5 for conversion, then through a power cord 6 plugging in the load. Under such a condition, electric power output from the backup power supply apparatus may be directly delivered to the load for use.

[0026] Furthermore, the backup power supply apparatus of the invention does not have environmental protection and recycle problems. In the event of disasters happen, it can provide power supply needed for the load and allow victims using the load to emit rescue signals to seek help.
